Excerpt from Henry Gannett: President of the National Geographic Society, 1910-1914 By his ingenuity in visualizing statistical results in many combinations, and the use of a variety of symbols devised to meet special conditions, he brought all branches of statistics within the ready comprehension of the people, and enormously increased their usefulness, particularly in schools, colleges, and public lectures. He thus made possible the introduction and successful use of the lantern slide in the teaching and understand ing both of geography and statistics. Nothing has since been developed in the graphic method which carries the art beyond his development of it. I recall a talk of hisat the cosmosclub many years ago, in which he lined the walls with colored drafts of the various symbols he employed, in an endless variety of combinations, suitable for any association of related data, and described the particular advantage of each in particular instances. I have often wished he had reduced that informal talk to writing, for I know of no treatise on the sub j ect more illuminating than this lecture.
